Slab Gate Valves With Ball Screw

This Slab Gate Valves with Ball Screw was special design according API 6A for large-bore applications and high pressure. The design eliminates the need for gear-type torque multipliers, and results quicker manual operation at full working pressure with remarkably low operating torque. The Slab Gate Valves with Ball Screw are made in all material class (AA…..HH), temperature range and PSL level requirements.
